DirecTV was doing free upgrades of SD equipment to HD equipment. I upgraded both receivers in the MH to HD receivers. Still work fine with the dome and receive all the SD channels. When they go away, will see what happens. For DISH, my dome will look at any of the three satellites but only one at a time. Called the dome manufacturer and they said that they MIGHT be able to replicate that operation for DTV, but nothing is in development yet. They are waiting to see what DTV does as well. Worst case, I just buy a Traveler and put it on the roof where the dome was.
